Free Cover Letter Builder

Yes, and there is nothing to sign up for. Every part of the builder is free: up to six paragraphs, reordering them, the named critique of each one, the term panel that reads a posting you pasted, all three tones and lengths, keeping several letters side by side, and copying, downloading as .txt or printing to PDF. No account, no card, no watermark, no upload. A free ResumeAI account adds exactly two things across these tools — AI rewriting and uploading an existing PDF or DOCX resume.

No. This tool is deterministic template assembly: it takes the role, the company, your paragraphs and your reason for wanting the job, and slots them into a structure using the connective phrasing of the tone and length you chose. The same inputs always produce the same letter. The critique next to each paragraph is a published list of rules — it names the words in your own sentence that triggered it and shows a fixed illustrative example, never one written from your text. The term panel counts how often a word appears in the posting you pasted and nothing more; it produces no match percentage, no ATS score and no rating. Nothing is generated, invented, or sent anywhere. AI rewriting is a separate feature of the ResumeAI app and requires a free account.

One page, and in practice well under it — a few short paragraphs: why you are writing, what you bring, why this company, and how you close. This builder offers three lengths, targeting roughly 150 to 200 words for Short, 200 to 300 for Standard and 300 to 400 for Detailed, and a live word count sits above the preview so you can see when you have drifted long. If a paragraph is not doing work that the resume cannot do, cut it.

It depends on the application. Many large-employer ATS flows make the field optional and few screeners read every letter, so a generic letter is wasted effort. A letter earns its place when you have something the resume cannot carry: a career change, an employment gap, a relocation, a referral to name, or a specific reason you want this company rather than the category. Write it when you have that; skip it when you do not.

Each paragraph is run through a published list of rules and every finding names the offending words in your own sentence. Passive voice, an auxiliary plus a participle such as 'was completed by'. Filler and hedging words. Whether the paragraph carries anything quantified. Sentence length, including any single sentence that has run past thirty-five words, and whether the paragraph as a whole sits in the 25 to 90 word band. It deliberately does not flag first person or a weak opening verb, because a cover letter is not a resume bullet and 'I' belongs in it. It is a rule checklist, not a model, not an ATS score and not a prediction.

No, and it never will. Paste a posting and the panel counts which words and two-word phrases it repeats, then lists them with a raw occurrence count and marks which ones already appear in your letter. That is the whole of it. There is no percentage, no match score, no ATS score and no rating, because a number computed from word counting in your own browser would look like a measurement and would not be one. The counting happens locally and the posting is never sent anywhere.

Yes. Name a letter, create another, duplicate one you like as a starting point, and switch between them from the bar above the builder. Each letter can hold up to six paragraphs which you can reorder, and you can export any of them as JSON and import it back later. They all live in this browser only, so exporting is also how you move a letter to another device.

In this browser's localStorage on this device only, under the key cvai:tools:cover-letter:v2. If you drafted a letter on an earlier version of this page, the older cvai:tools:cover-letter:v1 key is read once, adopted into the new one, and then left in place as a backup rather than deleted. It is never sent to a server. That also means clearing site data, using a private window, or switching devices loses the draft — copy it out, download the .txt or print it once you are happy with it.

Yes. The Download PDF button opens your browser's own print dialog with everything except the letter hidden, so you choose 'Save as PDF' as the destination and get a clean one-page document. There is no PDF library involved and nothing is uploaded to produce it. You can also copy the plain text straight into an application form.
